1 PRODUCT DESCRIPTION

This section describes the Digivance Neutral Host (NXD) Radio Access Node (RAN).

1.1

The RAN, shown in

Distributed Antenna System. The RAN is a pole-mounted or pad-mounted, weather-resistent

cabinet, housing electronic modules that operate on an internal cPCI backplane. Included are a

central processing unit, a system interface, an optical interface, optical to RF data converters,

RF multicouplers, and DC power supplies. The RAN also houses rectifiers, backup batteries,

power amplifiers, and optical wave division multiplexers. Optical and RF functions are both

required because the RAN exchanges data with the system Hub using an optical link and

exchanges data with wireless users using RF signals. Each RAN provides the system with an RF

antenna and can accommodate up to four bands (

RANs installed at the same location can accommodate up to eight bands using a common

antenna.
